This invention relates to improvements in: a method and machine for producing paper signatures, particularly for cutting and folding on one machine all of the signatures thatmay be printed upon large sized presses from sheets of maximum capacity. The present application is a division of m -copending application SerialNo. 281,657, led May 81, 1928.

Heretofore it has been customary to employ slitters in connection with printing presses of large capacity, in order to reduce the size of the sheets to the capacity of the folding machines available. For each printing machine operatiomtherefore, there are two or more folding machine operations. Obviously, the labor expense and the original equipment expense may be decreased by the use of a folding machine which can accommodate the full size sheets coming from the printing presses.

One ofthe objects of the present invention, therefore, is the provision of a machine capable of handling ina single operation the cutting and folding of signatures printed upon large size sheets such, for instance, as those having the dimensions of. approximately 4.4" x 66", from" which eight 16 page signatures or four 32 page signatures of average size may be made;

Another object is the cutting and folding of large size sheets-along lines such that it becomes feasible to cut and fold eight 16 age or four32 page signatures from a single s eet,

and to separately collect and stack the corre- .spondlng signatures of each sheet. I

A further object .is the provision of a method a'ndmachine-which will permit the slitting and foldingof eight 16 page signaemployed the workand turn form or the section having sheet deflectors adapted to.

close a' portion only of the mouths of the fold plates, so that sheets entering the fold section side by side may be reversely folded.

sorting and stacking mechanism which is by the line 1+1 of Fig. 2;

capable of ad ustment to handle either two orfour separate signatures.

Similar reference characters refer to like parts throughout the views.

In Figs. 1 and 2 I have illustrated one end of a sheet feeder comprising an upper feeding table 10 and a lower feeding table suitable type of feeder might be substituted.

Sheets of paper are delivered from the feeding table 11 onto a feed table 12 comprising diagonallv arranged rollers 13 driven by I be resiliently pressed toward the roll 16 by suit-able means so as to cause travel of the sheets forward and toward the left, as viewed from the rear or feed end of the machine. The table is provided with a guide bar 14 mounted for adjustment by means of screws 15. The diagonal arrangement of the rotating rollers 13 causes the guide edge of the sheet to contactwith the guide bar 14 and to be directed in a straight course thereby.

Beyond the delivery end of table 12 and adapted to receive sheets therefrom are a pair of feed rolls, the lower roll 16 of this pair being preferably cylindrical, while the upper roll comprises a shaft 17 carrying rubber surface wheels 18. The shaft 17 also carries slitting cutters or circular knives 19, 19, the cutter 19 being located centrally for cutting the original sheets intd two parts and the cutter 19 being located near, the side of the machine opposite guide 14 for trimming the rough edge of the paper to a line in exact parallelism with the guide edge thereof. {is indicated in Fig. 2, but omitted from Fig. 1 for-the sake of clearness, the shaft 17 may coil springs 20 adjustable as to'pressure by means of screws 21.

Beyond the feed rolls just described, and

preferably upon the same level with table 12, there is a feed table 22 having a central longitudinal division bar 23. On each s1de of this division bar the table carries a set of diagonally arranged driven rollers 24, 25, the rollers of; eachset having bearing in the outer side pieces of the table and in the central division bar 23. Along both outer sides of the table 22 there are guide bars 14' adjustable inwardly and outwardly bymeans of screws'15'.. The rotation of the rollers 24 and 25 carries the half sheets thereon out:

ward somewhat aswell as forward, and hence the sheets onthe table contactwith the guide Beyond the delivery end of table 22 I locate a fold section of the buckle fold type, consisting of a series ofrolls 26 and a series of fold plates 27. Theserolls and plates are of generally conventional form, but the sheet deflectors 28 used upon the fold plates extend but half-way across them. Two such deflectors may be employed upon each plate so as to deflect sheets delivered from both sides of the table 22, or one deflector only may be employed on a plate, as shown in Fig. ,9, so that one sheet isdeflected while the other is permitted to enter the plate. Where the latter arrangement is followed in the first fold plate the next succeeding plate is generally oppositely arranged as to deflectors, so that the sheets moving side by side on table 22 are reversely folded, that is, the upper surface of one of them is folded inwardly and the, upper surface of the other is folded out-' wardly. Any suitable means may be employed for mounting the deflectors 28 in operative position- Paper, upon leaving the last pair of rolls 26 of this folded section, is grasped b rubber wheels on feed rolls 30 and there y de livered into feed rolls 31. The shafts of this latter pair of feed rolls carry slitting cutters or knives 32 properly positioned to divide the two sheets passing through these rolls into four parts. These four parts drop onto.

located beyond the two ends of the table 33 are duplicates, except for the fact that they tion of one will serve for both.

Paper leaving an end of the table 33 enters the cross fold section, comprising rolls 40 and fold plates 41 of conventionalform. As is customary in this type of machine each plate may be closed a ainst the admission of sheet-s passing throug the section by means are rights and lefts. Consequently, a descrlpof a deflector. The number of plates in this section may be varied to suit condiitons, but

as a rule two plates, as shown, will be'sufiicient, as it is generally not desirable to impart more than one fold at this point, and the two plates will permit of making this fold in either direction as desired.

Which. are equipped with adjustable and rea gui e'bar 48, adjustab e by means of screws movable slitting knives 43. The feed table I 44 located beyond the feed rolls 42 is adapt- ;ed to handle either sheets received from table 33 in single fileor sheets delivered side by I side from the table 33,'aswhen the knives 43 are employed. The table is equipped with a set of diagonal driven rollers 45 and a side guide bar, 46, the latter being adjustable by means of screws 47. The, table is: also" equi ped with a readil removable auxiliary 49, and a tape'conveyor mounted upon a removable bracket 51, the tapes of this con veyor being positively di-iven .in any desired manner, as by means of the train of gears 52.

The conveyor 50 is above the level of the rollers 45 and is. adapted to convey sheets from the feed rolls 42 over a portion of the table 44 onto the rollers 45 beyond the line of the guide bar 48.

At the delivery end of the tabIe -44 there is a third fold section, ge'nerallyindicated by the reference numeral 55, which is parallel to the first named fold section. The section preferably contains two fold plates of con.- I ventional form, either or both of which may 'beclosedby means of sheet deflectors. The

deflectors used in this section preferably extendentirely across the fold plates in the conventional manner, 'but obviously half length deflectors,such as those illustrated in Fi 9 may be 'emplo ed if desired.

lllpon leaving the id d section 55 the paper enters a pair of feed rolls 56 which deliver it'onto a plate 57 and thence between feed rolls'58, 59. The latter rolls constitute part of a double sheet or signature sorting mechanism,either'side of which is'adapted to function independently of the other to deflect alternate signatures onto upper and lower stacking belts 60 and 61, res ctively, or the .twp'mechanisms maybe 100 ed together to-- function as a unit where, the livered" by sheet mile 56 travel n single file atures de onlly. Y a I v eferring new to Figs. 10 to'14, inclusive, it will be observed that .thereare a pair of w movable deflector elements .or flippers62, 62' mounted in alignment, These flippers tively, which their inner ends in an intermediate bracket- 7" 65.

longitudinall it? set screw 68' as. n loosened so as. to ermit pin 67 to enter socket 66 in order. to ock' the'two flippers togethen' Theparts may be 7 held in this position by again tightening the set screw 68. When. the pin 67 and socket 66 are disengaged the two flippers are free to 1 ca operate independently of each other., Each,

7 thick sheet flipper has-its own operating mechanism which is set in motion by the travel of sheets the' shoes71 that are actuated by the paper passing over the Wheels. 70, this being the means for setting in motion the flipper shifting-mechanism; The shifting of'the flip ers 62, 62' from the'pos'ition illustrated in ig.

ing metallic surfaces for cooperation with 11 to that illustrated in Fig. 12 and vice versa serves to guide the signatures passing in contact with the flippers into two different courses.

A bar 72 of rectanular cross section is A fixed in the frame. A racket-73 is mounted .upon the bar .72 and held in position by means of a set screw 74. A pintle 75 is fixed .in the bracket 7 3 by'means of a set screw 7 6, and projects laterally from the bracket to support, for pivotal movement a'bell crank "77. I A horizontal arm of the bell crank 77 is bifurca'ted for the reception and pivotal mounting of the crescent-shaped shoe 71,

heretofore mentioned, from the upper 'end of, which projects a pin 78.-

The upright arm of the bell, crank 77 is provided with an inclined head 79 which is perforated for the reception of a. stem 80 that is slidable to a slight extent in the head 79, and has a collar 81 which is fixed thereon for limiting suchsliding movement in one 1 direction. Sliding movement in the opposite direction is limited resilientlyby a coil fspring 82 surrounding the stem 80 and bearing at one end against the head 79 andat threaded in the bar 72 and is provided with the ether against a collar 83 fixed upon the t '80. The upperend of the stem 80 is a a. knurled head 86 bymeans of which itlmay' be turned, and with a knurled lock nut 87. By virtue of this arrangementv the pivot point for the shoe 71 may be adjusted accurately and held; positively against down-1 ward movement, but has the capability of v yielding slightly 'whene;\ 'e1--v an unusually of paper tends, to raise the shoe"7 1.-' W

In order to hold the hee 71th the normal position illustrated in Figs.,11 and 12 and to return .it to this i position after being swung upon its pivot by a sheet or signaturepassing throughe the .rolls 58, 59, I connect the upper end of the pin 78-with the fixed bar 72 by a tension sprlng 88.

In one wall of the frame above the shaft 59 I mount a stud 89 having a square head.

A pivot pin 90 is threadably mounted in the stud 89. On this pin 90 a bell crank lever 91 is pivotally mounted to swing horizontally through a small angle. The long arm of this lever has a bifurcated end Wh1ch strad- 1o dles the pin 78, by means of which motion is im arted to the lever whenever the shoe 71 swings upon its pivot. The Short arm of the lever 91 has a downturned lip 92 which is adapted, when in the position illustrated 1 in Fig. 10, to engage finger 93 or 93' -and The action of spring 88, above'mentioned. is limited by the fact that the bell crank 91 when in its shifted position to engage finger can swing no further, in response to the pull so a link 98, the opposite end of which is pivotally connected with a pin 99 or 99' that is attached to the flipper 62 or 62', as the case may be, near one corner thereof.

A gear 100 is loosely mounted upon the shaft 96 outside the frame and is continuously driven from gear 59 by means of an interposed idler 101. The gear 100, however, is pinned to a friction clutch 102 mounted upon the shaft 96. This clutch is shown in detail in Fig. 14. i It consists of two blocks 103 and 104 provided with curved friction pieces shaped to fit the shaft 96, the two blocks be.- ing resiliently drawn together by studs 107 acting through coil springs 108, it being evident that the degree of friction exerted upon' which meshes'with and is driven by the gear .100. The gear 110 and the shaft 109, therefore, rotate continuously. On the, inner end of the shaft 109 there is keyed a gear 112 which is adapted to mesh with the teeth of gear 95 when the toothed portions of'the latter are in a position to'permit such intermeshin e Y %etween the opposite Walls of the frame I mount ashaft 114 carrying feed rolls 115.

. A second shaft 116 is supported in bearings carried by brackets 117 extending inwardly from the frame on each side. This latter shaft carries feed rolls 113 cooperatin with the feed rolls '115. These rolls are a apted to receive sheets directed upwardly by the deflector 62, 62', when in the position of Fig. 11, and to deliver them onto the slowly moving stacker belt 60. When the deflector 62, 62' is in the position of Fig. 12 on thewother hand, the sheets are guided downwardly by the underside of deflector 62, 62' over a fixed deflector plate 119 onto the slowly running stacker belt 61.

The drive for the shaft 114 may come from shaft 59 through a-train of gears 120, 121, 122, the-latter gear being pinned to the shaft 114. Shaft 116 may be driven from shaft 114 bygears 123 and 124 insidethe machine frame as shown near the top of Fig. 10.

InFigs. 15 and 16 I have shown .in'a diagrammatic manner the method that I follow in cutting and folding a 128 pa e sheet on my machine. In these figures the ull lines indicate the cuts made in the sheet and the dotted lines indicate the folds. The sheet is divided by the cuts into four sections each having 16 pages and into eight sections each having 8 pages, the machine being adjusted and operated to fold together these eight page sections in pairs, thereby producing eight 16 page 'signatures from a. single'sheet. Fig. 15 is intended to represent a 128;page sheet of the sheetwise form. The paging may be varied more or less, and is not indicated inthe figure. Fig. 16 is similar to Fig. 15, but illustrates a paging which maybe employed in connection with my method of cutting and folding where the work and turn form of sheet is used. In this figure the page numbers on the upper side of the sheet are shown in full lines and those on the lower side of the sheet in dotted lines. This form of sheet, as is well known in the art, produces two half sheets of 64 pages each.

. In Fig. 1, I have shown at A a'sheet of large size capable of being divided and folded into eight 16 page or four 32 page signatures of average size. B, B represent two half sheets obtained by cutting in two the sheet A. C, C C and 0 represent four quarter sheets, each having a single fold, formed by first folding and then cutting in two each of the half sheets B, B D, D'*, D and D represent sections of one-eighth of the full size of the original sheets and are formed by folding and then cutting in two each of the *two, quarter-size sheets C, C", while E, E,

E and E represent complete signatures formed by' folding and cutting intwo each' of the quarter size sheets C and C and then folding them again. It will be noted that sections D and D as well as the signatures sections D and D and the signatures E and E are each in-two pieces folded together.

"Operation Assumingfi rst that it is desired to cut and E and E are each in one piece, while the by the knife 19. The two half sheets are then deposited upon the table 22, the rollers 24 carrying sheet B to the left and the rollers 25 carrying sheet B to the right,'the edge trimmed by the cutter 19 constituting. a square edge parallel to the guide edge of the sheet A for contact with the guide bar-14'- on theright side of the table 22, while theoriginal guide edge of half sheet B runs upon the guide bar 14 at the left of the table. The two half sheets B and B, therefore, travel forwardly upon the table 22 side by side and in exact parallelism.

It is necessary that the upper surface of'the half sheet B be folded inwardly while the upper surged of the half sheet B -must be folded outwardly. Consequently, the first fold plate of the first fold section is arranged with a deflector on the right-hand side only, that is to say, reversely to the arrangement illustrated in Fig. 9. The second fold plate of the same'section is arranged with a deflector on theleft-hand side only, as shown in Fig. 9, and the two remaining fold plates each have deflectors extendingentirely across the same. Hence, half sheet B has one in-.

ward fold imparted to it and half sheet B has one outward fold imparted-toit, in this fold section.- Q 1 Both of the half'sheets B, B, emerge at substantially the same time from this first fold section and pass through feed rolls 30 and 31. The-cutters 32 onthe latter-rolls slit the folded half sheets B and B into the four quarter sheets- 0 and C, C, C, and ,the latter are all dep'osited onto'table33 simultaneous'ly, or substantially. so.

interval between the instant the rear edge of the signature E leaves the rolls 58, 59 and the-instant the .forward edge of the succeed ing signature that is the one corresponding to the section begins to be engaged by these rolls. Consequently, when the second signature advances through the rolls the flipper 62 is in position to guide the signature downwardly against the guide plate 119 and thence onto the lower belt 61.

If it beassumed that the flipper 62 is also in the position illustrated in Figs. 11 and 13, when the signature E, passes this flipper, that signature also will be directed upwardly and onto the same belt conveyor 69 as the signature E the two rows of signatures on the belt being spaced apart suficiently to prevent any possibile intermingling. The two sections E and E do not pass through the flipper mechanism at the same time and, therefore, it. is necessary to operate the two fi1ppers 62 and 82 independently. it will be noted also that these mechanisms are not timed with respect to other operations performed upon the machine, but that they are controlled entirely by the travel of the signatures themselves.

When the signatures corresponding to sections D and D approach the sorting mechanism, the flippers 62 and 62 are in the position illustrated in Fig. 12, and these signatures therefore are deflected onto the lower belt conveyor 61, their passage through the sorting mechanism causing the resetting of the flippers to the position of Fig. 11 ready for the next succeedin pair of signatures.

The movements of the parts are the same for each operation except for the fact that the link 98 moves downwardly in one operation due to the movement of the crank; pin 97 through one-half revolution from upper center to lower center, and upwardly in the next succeeding operation due to the movement of the crank pin 97 through the upper half of its revolution.

The quarter sheets C? and C are acted upon in a manner similar to that described with respect to quarter sheets C and C except that the second and third fold'sections on the ri lithand side of the machine are set to fold t' e upper surface of the paper outwardly instead of inwardly.

The belt conveyor 50 and the guide bars I 48 are made removable, so that when the printing on the quarter sheets 0 and C is identical the sigantures commg from each side of the machine may be stacked in two piles instead of four.. Under such circumstances the slitters 4:3 may or may not be used. l/Vhen the machine is-thus set upfor single file travel of paper sections along the table 44;, and particularly if the signatures are wider than one of the flippers 62, 62 I loosen the set screw 68 and slide the fiipper 62' inwardly, causing the pin 67 to enter the socket 66 and the crank pin 99 to be withdrawn from engagement with flipper 62 after which I again tighten the set screw 68. The two flippers then function as one.

It will be obvious also that it the character of the printing upon the original sheet calls for such manipulation, the table 44'011 one side of the machine may be arranged to carry paper sections in single file, while that on the opposite side is arranged for signatures traveling in two parallel paths, the sorting mechanisms on the two sides being adjusted accordingly.

It will be obvious further that while the machine is particularly adaptable for handling 128 page sheets, the number of pages may be either increased or decreased and be made, and itis quite'possible to use the same machine set up for both sheetwise and work and turn forms if the sheetwise forms are rinted with this object in" mind.
